Background and Aim: The number of elderly population in the world and also in Iran has increased due to health improvements and therefore, the quality of life has been focused in this group of population. Physical disabilities and particularly balance disturbances are among the consequences of the ageing process and hence, would affect the quality of life in elderly population. Mental practice is in fact the cognitive review of a physical skill without performing obvious bodily movements. The purpose of this study was to investigate the effect of mental practice of a movement skill on improvement of the quality of life in elderly men (60-80 yrs).

  

Materials and Methods: This was a Single blind Randomized controlled trial (RCT) study. The study was approved by the research ethics committee of the Tehran university of medical science (Irct ID: IRCT201107041722N3). The elderly population was 44 elderly men (60-80 yrs.) who were living in Kahrizak Nursing Home. They were randomly assigned in two groups and entered the study based on inclusion criteria. After baseline assessment, the quality of life of all of participants were assessed by SF36 test and also at 3 various stages (i.e. respectively, before the beginning of ,baseline assessment two weeks after intervention ,short term follow up and 3 months after intervention, long term follow up). Elderly population in the intervention group did mental practice of one movement skill for 4 weeks and during this periods, the control group did no mental practice.

  

Results: The results of our study showed the scores of SF36 in physical component, after the intervention of mental practice, have had a significant difference between the control and intervention groups. Although test scores in mental component and the whole test score showed no significant difference between the case and control groups at 3 stages of assessments.

  

Conclusion: The results of this study showed the significant effects of mental practices on physical component of SF36 in elderly population. However, these results also showed that this type of mental practice had no significant effects on mental component and total score of SF36.

Background and Aim : One of the most common defects observed after stroke is deficit in trunk control and balance which can lead to disability or dependency in many functional activities in life. Many therapeutic approaches are used in the rehabilitation of stroke patients, but there is no any unique accepted approach in this field yet. However there are many evidences that show task-oriented practice for neuro-movement rehabilitation can be efficient. The purpose of this study was to examine the effect of intensive task-oriented balance practices on functional balance and mobility in patients with chronic stroke.

  

Materials and Methods: This study was an intervention - quasi-experimental with chronic stroke on 13 patients (study on 4 women, 9 men, mean age 55/07 ± 8/41)which were selected according to inclusion criteria. The intervention included 10 days of intensive practice during 2 weeks , 5 days per week for 3 hours a day. The assessments (Berg Balance Scale, Time Up and Go) were performed before and after the intervention.

  

Results: Intensive task-oriented balance training in patients with chronic stroke significantly increased the functional balance (p=0/005) and reduced the time of functional mobility (p=0/001)

  

Conclusion: The results showed that intensive task-oriented balance training can improve functional balance and functional mobility. Because this study was done only in one group, conducting more studies with appropriate control group is suggested. Follow up were recommended in order to show durability effect for future researches.

Background and Aim: Scapular muscles stabilization and neuromuscular control are important factors in shoulder function during dynamic activities. The three-dimensional pattern of integrated movement between gleno-humeral and scapula-thoracic joints is known as the scapula-humeral rhythm. More involved rotator cuff and scapular muscles causes more motor units are being recruited, therefore perhaps with loading on scapular muscles, can evaluate muscles role in scapular position more accurately and comprehensively.

 

Materials and Methods: Thirty male basketball players, aged between 20 to 40 years were recruited for modified lateral scapular slide test. The linear distance between inferior angle of scapula and spinous process of T7-8 was examined in 90 degrees of scaption without load and with 1 kg loading by two examiners in one session using the caliper. One of the examiners repeated the test in next week.

 

Results: Amount of inter and intra-rater intra-class correlation coefficient (ICC) for 90 degrees of unloaded scaption was 0.73 and 0.82, respectively and for 1 kg loading position was 0.54 and 0.86, respectively. Amount of standard error of measurement (SEM) in inter and intra-rater measurements for 90 degrees of unloaded scaption was 0.83 and 0.59 cm, respectively and for 1 kg loading position was 0.97 and 0.45 cm, respectively.

  

Conclusion: 1 kg loading in scaption, did not significantly improve the reliability of the test that shows the amount of load is not appropriate to activate the muscles in the athletes.

Background and Aim: An immaculate review of the literature reveals some changes on the vertical ground reaction force (VGRF) in ACL deficient knee subjects. However, the details are not clear yet. The current study aimed to study these changes in the ACL-deficient and apparently healthy knees of the coper and non-coper ACL-deficient knee subjects in comparison with the normal knees.

Materials and Methods: Sixteen unilateral ACL-torn subjects included 8 copers and 8 non-copers were recruited in this quasi-experimental study and were compared with 16 normal knee subjects (8 subjects matched to each coper and non-coper groups). All subjects walked barefoot and with their preferred speed in a 6-meter walkway and placed their wanted foot on the platform of a Zebris pedobarograph tool. The patients were asked to place their injured and healthy feet separately on the platform. The control group placed their foot matched to the ACL-deficient legs on the platform. The testes were repeated so much to have five acceptable trials. The outcome measures included the peak F1Z, F2Z, F3Z of the vertical ground reaction force values and the times to reach these peak values as well as total stance time of the tested feet.

Results: The results showed only a significant lower F₁Z value in the non-coper ACL-deficient knee subjects (p=0.008). No significant changes were shown in the F₂Z, F₃Z or the times reach to F₁Z, F₂Z and F₃Z values (p>0.05). The stance time of the coper ACL-deficient knee subjects increased significantly in the non-coper ACL-deficeint knee subjects when compared to the coper and healthy knees (p=0.005).

Conclusion: The reduced F1Z of the vertical ground reaction force at initial contact as well as increased total stance time seen only in non-coper ACL-deficient knee subjects reveals inadequate compensatory mechanism in these patients as a counter force stress at initial contact and weight bearing. However, the coper ACL-deficient knee subjects compensated these forces with good strategies and walked very similar to the control group.

Background and Aim: Despite the widespread use of whole body vibration (WBV),especiallyin recent years, its neurophysiological mechanism is still unclear and the results about the facilitatory or inhibitory effects of WBV widely vary in different studies. The aim of this study was to compare between immediate (one session) and short term (12 sessions) effects of WBV on the spinal motor neurons excitability in healthy young men.

  

Materials and Methods: Ten voluntary non-athlete healthy young-men (mean age:26.1±2.23) were participated in this study.In the sham sessions subjects stood on the turned off vibration plate while were maintaining the semi-squat position and then after 2 weeks wash-out, vibration training sessions were done on the same position with frequency of 30 HZ and peak to peak amplitude of 3 mm training sessions (sham & vibration) consisted of 12 sessions (3 sessions per week) and 4 set in each of them, weekly one set added to the training protocol. H reflex recruitment curve of soleus muscle was recorded before and after first and also 12th sessions in both sham and vibration training protocol. Ascending slope of recruitment curve, threshold and peak amplitudes and related intensities, amplitude of Mh and Hmax/Mmax ratio were determined.

  

Results: Immediate effects of vibration training 12th session caused a significant decrease of threshold amplitude and an increase of peak intensity (p=0.05 and p=0.05 respectively). Short term WBV training significantly decreased the threshold intensity of soleus recruitment curve (p=0.01).

  

Conclusion: The results suggest the inhibitory effect of acute WBV training on the spinal motor neurons excitability. It seems that short term WBV training may be effective to facilitate the motor neurons excitability or increase the muscle spindle sensitivity.

Background and Aim: Transcranial Magnetic Stimulation is a novel technique for inhibition or excitation of brain cortical area. Dichotic listening test is a simple instrument to determine dominant ear and brain hemisphere for processing of verbal stimuli. This study aimed to determine changes in right ear advantage(REA), after applying inhibitory rTMS protocol on left Broca area.

 

Materials and Methods: In this descriptive - cross-sectional study, we compared the performances of 14 right handed normal adult Persian speakers with normal auditory and no history of psychiatric or neurological disorders. TMS was applied at 1 Hz with 90% motor threshold, for 10 minutes (600 pulses) on left Broca's area. The right ear advantage index was assessed pre and post rTMS using dichotic listening test.

  

Results: Finding of the present study showed no significant difference on right ear advantage index pre and post rTMS using paired t-test.

 

Conclusion: According to the findings of this study, it can be concluded that the use of inhibitory rTMS protocol on the left Broca area , has no effect for shifting in the right ear advantage. For interpretation of the results, it could be stated that it may be the protocol was used in this study isn't sufficient enough to inhibit left hemisphere for linguistic processing. Another reason could be the lack of sufficient sensitivity of Dichotic Listening test to show changes in hemisphere function after TMS. However, to provide clearer description, using functional brain imaging techniques and TMS together could be helpful.

Background and Aim: Low back pain (LBP) is the most common and expensive musculoskeletal problem in industrialized societies. One in ten people suffers from LBP once in his life. It is self-limited up to 90%, but it is common to repeat. By the way, sacroiliac joint (SIJ) is the origin of low back and pelvic pain in many cases and one of the most important elements in normal musculoskeletal function during gait cycle. Muscles are important to stabilize this joint plus to bones and ligaments. Some of the muscles (Gluteus Maximus, Biceps Femoris, Multi Fidus, Erector Spinae) contributing in gait cycle are important to transfer load through SIJ. The aim of this present study is to compare muscle activity timing during initial and mid stance phase of gait cycle.

  

Methods and Materials: Sixteen low back pain cases and fifteen healthy subjects participated in this study. A footswitch is placed beneath foot at the suffered side in LBP cases and dominant foot in control group. Two markers were on the 5^th metatarsal bone and lateral maleolus. Electrodes are placed on selected muscles according to SENIAM. Digital camera and EMG Datalink were turned on simultaneously and subject started to walk with his own favorite speed in a specific direction and path. Onset and time to peak of selected muscles were recorded during gait by Datalink and processed by its software.

  

Results: Low back pain cases showed delayed muscle onset, although it was not significant (P=0.4). Time to peak of all selected muscles in loading response event in LBP group was longer and significant (P=0.01). There was also significant difference in time to peak of all selected muscles during mid-stance event (P= 0.005) except biceps femoris muscle.

  

Conclusion: Delayed onset and longer time to peak during initial and mid stance phase of gait can be interpreted as a compensatory strategy to control trunk movements effectively, provide sufficient stability and transfer load to lumbar area efficiently.
